VI, ii. This sub-family is confined to the temperate and subarctic regions 

 of the northern hemisphere ; the genera are all different from tliose recog- 

 nized on the other coniinent, though it is quite possible that some of them 

 may be represented in Nortliern Asia. 



VI, iii. Ilhycerus is an entirely isolated form, having no relations to 

 other genera, so far as known to me. 



VI, iv, 1. One species of Phytonomus and two of Lepyrus are common 

 to the subarctic regions of both continents. Listronotus and Macrops prob- 

 ably extend into tropical America, but a renewed study of the old genus 

 Listroderes must be made before this can be definitely stated. 



VI, iv, 3. This peculiar maritime fossorial tribe is represented hj a dif- 

 ferent genus in Australia. 



VI, iv, 3. Plinthus, Hylobius, and Pissodes, are confined to the northern 

 hemisphere, but may be represented {teste Schouherr) in Brazil and Aus- 

 tralia. Hilipus is largely represented in South America, but not on the 

 other continent, unless II. orieiitalis'Motsch, from Japan, should on proper 

 examination prove to belong to the genus. 



VI, iv, 4. The genera in this tribe are very indefinite, and the foreign 

 species still require revision to bring out the facts in geographical distribu- 

 tion. Lixus, Cleonus, and Stephanocleonus, are the only examples I can 

 mention at present of genera common to both continents. 



VI, iv, 5. Procas picipes. two species of Grypidius and TanyspJiyrus 

 lemnm, are common to the northern part of botli continents, and have not 

 been introduced. The only genus which extends to Tropical America is 

 Phyllotrox. 



VI, iv, 6. Trachodes is subarctic, and occurs on both continents. 



VI, iv, 7. Otidocephalus is peculiar to North and South America. 



VI, iv, 8. Magdalis is cosmopolitan, but most largely represented in 

 Europe and North America. 



VI, iv, 9 Anthonomus is cosmopolitan, or nearl}^ so. Orchestes is con- 

 fined to the nortliern hemisphere. The other genera in our fauna are new, 

 and their distril)ution is consequently unknown. 



VI, iv, 10. This tribe seems to be exclusively American, but both genera 

 extend into the southern tropics. 



Vr, iv, 11. The tribe Tychiini has not been separated from Erirhinini 

 sufficiently accuratelj^ to make any observations of value at present. 



VI, iv, 13. I do not know if the species common to Europe and America 

 have been introduced or not. The tribe, by the diminished number of 

 joints in the funicle of the antennae indicates a low grade, and the genera 

 are widely diffused on the eastern continent, but do not occur in South 

 America or Australia. 



VI, iv, 13. This small tribe is represented on both continents ; the spe- 

 cies have not been studied with sufficient care to indicate the distribution 

 of the genera. 



VI, iv, 14. This tribe is American, and best represented in the tropics. 



VI, iv, 1.5. With the exception of Acalles, Cryptorhynclms, and Coelo-
